Willwarn uses onboard ABS, ESP, EBD and GPS systems to
monitor hazardous road conditions (fog, black ice, pot holes, etc.) or broken
down vehicles. The data accumulated is then transmitted via an ad-hoc WiFi
connection to following or oncoming vehicles within a 500 meter radius. Cars
near the edge of the 500 meter radius of a signaling vehicle can also become a
beacon to relay data to more vehicles.

The information collected is then displayed to the driver so
that proper precautions can be taken to avoid or safely navigate problem areas
on the road.

DaimlerChrysler hopes to have the new system in place by the
end of the decade with high-end Mercedes and Maybach models most likely getting
first dibs.
